#2 - McGregor wasn't on form

After knocking it out the park in Toronto, McGregor didn't have the best time on the microphone.

The crowd never seemed to get into his shtick and to be fair, it wasn't his strongest material of the tour.

He made a good start with his reference to the Notorious B.I.G but he'll need to go back to the drawing board before he hits the stage in London.

Whether it was just the long wait or fatigue of the tour itself, McGregor's speech just didn't hit the mark.

#3 - Mayweather didn't have a good time of it either

After McGregor's monologue fell a little flat, Mayweather had the stage set for him to take full advantage.

But aside from the odd good line and a tense moment where he nearly incited a ruckus between the two camps, Mayweather didn't have much to say.

The boxing champion threw a bag of money in the air, but McGregor quickly pointed out, "They're all ones."

Mayweather then went on to point out McGregor had tapped out three times in his MMA career, but that's all he had before the two faced off again to close the show.

Give what had gone before, it was easily the weakest night of the three so far.

#4 - Mayweather vs McGregor will be the only MMA vs boxing fight on the card

It's been widely speculated about for a few weeks now, but Showtime's Stephen Espinoza confirmed that McGregor vs Mayweather will be the only fight on the card showcasing boxing against mixed martial arts.

Espinoza then also revealed that the pay-per-view portion of the card will feature four fights including the Mayweather vs McGregor bout.

No other fights have been confirmed for the card, but Badou Jack, who drew with James DeGale earlier this year, and Gervonta Davis, are expected to feature.

#5 - The waiting game...

We got a little taste of it on the second evening, but last night things were much worse as both fighters made the fans wait for the start of the press conference.

After the excitement the night before, fans eagerly tuned in shirtly before midnight in the UK, only to find themselves sitting around for over 90 minutes until the programme even started.

It was another 30 minutes before the two fighters hit the stage and only after a painful attempt by Doug.E. to whip the crowd up into a frenzy with some old school hip-hop.
